Characteristics of West German demand for international tourism in the northern Mediterranean region

The purpose of this paper is to establish the economic determinants of West Germany's demand for international tourism in six northern Mediterranean nations. The methodology makes use of the translog utility function. Homotheticity and additivity restrictions of the utility theory are tested as hypotheses. Expenditure (income), own and cross-price elasticities are claculated for each of the twenty years from 1966 to 1985.     

A dynamic econometric model of Thailand manufacturing energy demand

The purpose of this article is to employ the dynamic translog framework to model inter-factor and inter-fuel energy demand for the Thai manufacturing sector. The Denny et al. (1981) and Lynk (1989) framework, which proposes a dynamic adjustment for capital stock is employed to motivate the estimated of factor demand and fuel share equations. Three factors: energy, labour and capital; and five fuel types: fuel oil, diesel oil, liquified petroleum gas (LPG), electricity, and coal and lignite; are examined. Regression diagnostics support the empirical specification. Numerous factor and fuel substitution possibilities are identified, with some policy implications described.     

A system of equations model of UK tourism demand in neighbouring countries

This paper uses a system of equations model to examine tourism demand during periods of destination country transition and integration into the wider international community. The Almost Ideal Demand System model is applied to the UK demand for tourism in the neighbouring destinations, France, Spain and Portugal. Spain and Portugal are interesting cases as, during the period under consideration, they experienced a process of transition from economies with characteristics typical of developing countries, only entering the World Bank's industrialized countries classification in the 1980s. The paper examines the evolution of tourism demand during these countries' transition from ‘developing’ to ‘developed’ status. Consideration of France as a neighbouring destination also allows the behaviour of tourism demand to be compared between relatively rich and poor countries. The results show the extent to which the cross-country behaviour of demand becomes more or less similar over time with respect to changes in expenditure and effective prices. The expenditure elasticities are greater for Spain than France during the initial period, indicating that tourism can assist countries to ‘catch-up’ with their richer neighbours. However, this outcome is not always the case and may not persist, as Portugal had a low initial expenditure elasticity and Spain's relatively high expenditure elasticity decreased over time. Destinations' sensitivity to changes in their own and competitors' prices can also change over time, as indicated by the increases in the own- and cross-price elasticities for Spain, compared with the decreases for France and Portugal. The cross-price elasticity estimates indicate substitutability between the immediate neighbours, Portugal and Spain, and France and Spain.     

A study on tourism development model with dynamic mechanism of circular economy

With the social and economic development,conflict among the shortage of resources,environmental destruction and economic development is ever more pronounced.In this context,the circular economy was gradually accepted.Guided by sustainable development concept and promoted by six external forces,tourism circular economy take tourism micro-cycle model as the core,implement in corporate and social levels,improve resource utilization efficiency,reduce tourism＇s adverse impacts on the surrounding environment through recycling,reducing and reusing resources,achieve economic,social and environmental development of the organic unity.     

R&D activity in a dynamic factor demand model

The focus of this paper is an econometric analysis of the determinants of private firms' R&D activities in the context of a general dynamic factor demand model. Besides the traditional production factors we treat technological knowledge, endogenously determined by R&D expenditures, as a further input factor. While labour and materials are assumed to be variable, capital and know-how are considered as quasi-fixed. The dynamic demand equations for labour, capital investment and R&D which are derived from an intertemporal cost minimisation are estimated for a panel data set of small and medium size German firms. The data covers the period between 1978 and 1982 and includes 408 firms. It turns out that R&D activity depends on the underlying production structure as suggested by neoclassical theory. In addition, by introducing firm specific effects, we can show that firm size and market concentration influence innovative behaviour in accordance with the Schumpeterian hypotheses.Paper presented at the Industrial Organization Conference at the Annual Meeting of the Austrian Economic Association, Vienna, June 24–26, 1992, the 7th Annual Congress of the European Economic Association, Dublin, August 29–31, 1992, and the 19th Annual Conference of the EARIE, Stuttgart, September 4–6, 1992. Helpful suggestions and comments were received from participants of these conferences as well as from seminar participants at Temple University, at the University of Augsburg, and at the fourth DFG workshop Marktstruktur und gesamtwirtschaftliche Entwicklung in Munich. We are particularly indebted to an anonymous referee for very helpful specific comments. Finally, we would like to thank Horst Albach for providing us with the panel data set.

Dynamic analysis of British demand for tourism abroad

This paper investigates how preference endogeneity, in the form of habit persistence, can affect short-run and long-run tourism expenditure decisions. The proposed model is applied to British quarterly data over the period 1979–91 and the empirical results suggest that preference endogeneity appears to have an important effect. This has policy implications for countries competing for British tourist arrivals. The differences between the short-run and long-run price and budget elasticities which are implied by habit persistence are also investigated.     

Estimating dynamic demand for airlines

This paper uses an original panel dataset with posted prices and sales to estimate a dynamic demand. We find that consumers become more price sensitive as time to departure nears which is consistent with having lower valuations. This result provides empirical support to a key theoretical implication in Deneckere and Peck (2012)—high-valuation consumers purchase earlier. We also find that the number of active consumers increases closer to departure.     

Sun,sand and September 11: a model of tourism demand for the Maldives

Tourism is a key source of income for many small island economies, and so it is important to understand its determinants in such countries. We estimate a tourism demand model for the Maldives’ five main source markets and find that, in addition to the usual foreign income and own price variables, the cost of travel and of visiting alternative destinations (often missing from studies of this nature) almost always have a significant role. In addition, the country’s own marketing efforts prove effective at influencing demand. Finally, we find evidence the War on Terror has persistently depressed demand from some markets.     

Competition in tourism among the Mediterranean countries

This paper examines tourism competition among the Mediterranean countries with particular emphasis on Greece. The estimated model includes as explanatory variables an income index, a price index of the host country, a price index of the competitors (Spain, Portugal and Italy) and exchange rate. The results show that the main determinants of Greece's tourism demand are both price indexes and exchange rate. They also show that Spain seems to be Greece's main competitor.     

A dynamic approach to voluntary environmental contributions in tourism

In an evolutionary game-theoretical model of tourism firms that use an endogenous natural Common Pool Resource (CPR) we show that stable equilibria with voluntary environmental initiatives may coexist with other equilibria where voluntary abatement is absent. The basins of attraction of the equilibria are identified and a bifurcation analysis is carried out producing two results with policy implications. First, there is a highly non-linear relationship between the cost of abatement required to be green and the share of green firms. Second, increases in the number of the CPR's users will ultimately dissipate the incentives to make abatement beyond regulation.     

Dynamic and stochastic structures in tourism demand modeling

In this paper we consider a model for international tourism demand. The point of departure of the analysis is a utility function that is both dynamic and stochastic. In the model the stochastic component is interpreted as random changes in preferences for goods and services, while the dynamic component can be seen as either habit formation or as interdependent preferences. The resulting demand functions are estimated as a multivariate state space model, where the stochastic components enter the model as stochastic seasonal and trend components. An application is constructed for different segments of the Swedish tourism market. The results indicate the importance of including both dynamic and stochastic components in the utility function, and the importance of using disaggregate data to enable investigation of each market segment.I am grateful to two anonymous referees for useful comments.

A dynamic model of settlement

We investigate the role of settlement in a dynamic model of a payment system where the ability of participants to perform certain welfare-improving transactions is subject to random and unobservable shocks. In the absence of settlement, the full information first-best allocation cannot be supported due to incentive constraints. In contrast, this allocation can be supported if settlement is introduced, provided that it takes place with a sufficiently high frequency.     

A dynamic factor model framework for forecast combination

A panel of ex-ante forecasts of a single time series is modeled as a dynamic factor model, where the conditional expectation is the single unobserved factor. When applied to out-of-sample forecasting, this leads to combination forecasts that are based on methods other than OLS. These methods perform well in a Monte Carlo experiment. These methods are evaluated empirically in a panel of simulated real-time computer-generated univariate forecasts of U.S. macroeconomic time series.     

Cointegration analysis of quarterly tourism demand by Hong Kong and Singapore for Australia

Hong Kong and Singapore are two of the most important and fastest growing markets for tourists to Australia. The purpose of this paper is to investigate movements in the long-run demand for tourist travel by these two origin countries for Australia. Some of the leading macroeconomic variables examined to explain tourism demand are incomes in Hong Kong and Singapore, tourism prices in Australia, and transportation costs and exchange rates between the two countries and Australia. Seasonally unadjusted quarterly data are used for Hong Kong for the period 1975(1)–1996(4), and for 1980(4)–1996(4) for Singapore. Several proxy variables are used for the incomes of tourists from Hong Kong and Singapore to explain quarterly tourist arrivals to Australia. The augmented Dickey-Fuller test for unit roots is examined in the univariate framework, and Johansen's maximum likelihood procedure is used to test for cointegration and to estimate the number of cointegrating vectors. Error correction models are estimated to explain quarterly tourism demand by Hong Kong and Singapore for Australia.     

A fast estimation procedure for discrete choice random coefficients demand model

We document speed-up gains of graphical processing unit (GPU) computing over central processing unit (CPU) for the estimation of discrete choice random coefficient demand model. When we use a moderate-sized GPU, the computation is six to twenty times faster, where the smallest speed-up factor, six, is obtained from a comparison with the parallel computing over sixteen CPU cores.     

A two-dimensional non-equilibrium dynamic model

This paper develops a non-equilibrium dynamic model (NEDyM) with Keynesian features (it allows for a disequilibrium between output and demand and it considers a constant marginal propensity to consume), but where production is undertaken under plain neoclassical conditions (a constant returns to scale production function, with the stocks of capital and labor fully employed, is assumed). The model involves only two endogenous/prognostic variables: the stock of physical capital per unit of labor and a measure of market disequilibrium (MMD). The two-dimensional system allows for a careful analysis of local and global dynamics. Points of bifurcation and long-term cyclical motion are identified. The main conclusion is that the disequilibrium hypothesis leads to persistent fluctuations generated by intrinsic deterministic factors. These fluctuations may reflect some of the features frequently encountered in observed business cycles, once the model is conveniently adapted to this purpose.     

An empirical study of outbound tourism demand in the UK

A general to specific methodology is used to construct UK demand for outbound tourism models to twelve destinations. A tourism destination preference index is introduced to take into account social, cultural and psychological influences on tourists' decisions concerning their overseas holiday destinations. The tests support the existence of a cointegration relationship for each of 11 UK overseas holiday destinations. The corresponding error correction models are estimated. The empirical results show that the long-run income elasticities for all destinations range from 1.70 to 3.90 with an average of 2.367. The lowest and highest short-run income elasticities are 1.05 and 3.78 respectively, with an average of 2.216. The estimates of the income elasticities imply that overseas holidays are highly income elastic while the own-price elasticities suggest that the demand for UK outbound tourism is relatively own-price inelastic. In terms of the significance of substitution prices in the regression equations, Ireland is the favourite substitute destination for UK outbound tourists. Ex post forecasts over a period of six years are generated from the ECM models and the results compared with those of a naive model, an AR(1) model, an ARMA(p,q) model, and a VAR model. The forecasting performance criteria show that the ECM model has the best overall forecasting performance for UK outbound tourism.     

A dynamic model of unsecured credit

We study the terms of credit in a competitive market in which sellers (lenders) are willing to repeatedly finance the purchases of buyers (borrowers) by engaging in a credit relationship. The key frictions are: (i) the lender cannot observe the borrower?s ability to repay a loan; (ii) the borrower cannot commit to any long-term contract; (iii) it is costly for the lender to contact a borrower and to walk away from a contract; and (iv) transactions within each credit relationship are not publicly observable. The lender?s optimal contract has two key properties: delayed settlement and debt forgiveness. Finally, we study the impact of changes in the initial cost of lending on the contract terms.     

A dynamic model of altruistically-motivated transfers

This paper studies a dynamic Markovian game of two infinitely-lived altruistic agents without commitment. Players can save, consume and give transfers to each other. We identify a continuum of equilibria in which imperfectly-altruistic agents act as if they were a perfectly-altruistic dynasty which is less patient than the two agents themselves. In such equilibria, the poor agent receives transfers until both effectively pool their wealth and tragedy-of-the-commons-type inefficiencies occur. We also provide a sharp characterization of strategic interactions in consumption and transfer behavior. This provides new insights relative to existing two-period models. It allows us to differentiate between the Samaritan's dilemma – e.g. a child runs down its assets inefficiently fast in anticipation of transfers – and what we refer to as the Prodigal-Son dilemma – e.g. parents do not leave an early bequest, anticipating a child's profligate behavior.
